Only thing I can think of is to make sure on your sanding that you're going both directions. In other words, if you go lengthwise on a tube (for instance) the first time, go across the length as well at a 90 degree angle to the first sanding. Use a bright light and watch to see if anything shows up that isn't going the direction of the 2nd sanding. That's good practice with all the steps, tho it's not always possible on all shapes.
